县级电力综合业务数据城域网的设计与应用

文章分析了目前传统县级电力信息网的现状,根据县级供电企业信息通信业务发展需求和趋势,提出了适合未来县级电力企业发展的综合业务数据城域网的组网设计方案。通过对目前电力企业信息网组网的主流技术及成功案例的借鉴,提出了融合开放最短路径优先（OSPF）和同步数字体系（SDH）的技术组网方式。文章简要介绍了OSPF的技术原理,具体说明了OSPF与SDH的融合方法,详细介绍了交换为主网、传输为备网的双层县级电力综合业务数据城域网的保护方式,提出了基于OSPF＋SDH技术的县级电力综合业务数据城域网的设计建设方案。

Design and Application of County Electric Power Integrated Service Data Metropolitan Area Network

This paper analyzes the situations of the traditional county electric power information network, and puts forward a networking design solution of the integrated business data Metro Network Design in order to meet the future development of the county power enterprises according to the development requirements and trends of information communication businesses in county level power supply enterprises. The networking design solution uses a combinatory of OSPF and SDH by referring to successful cases and the current mainstream technologies. This paper describes the method of integrating OSPF with SDH in details alter the brief introduction of OSPF technical principle, as well as the protection mode used in dual-layer county power integrated service data network with exchange as master network and transmission as slave network.
